What are two advantage of legume crops?
They have nodules on the roots which has nitrogen fixing bacteria
The relationship between legume plants and bacteria that helps the nitrogen cycle is called?
nitreu
What relationship exists between the bacteria in the soil and legume root in nitrogen fixation?
Gass
Where do nitrogen fixing bacteria that have a symbiotic relationship with legumes live?
Legume plants are notable for their ability to fix atmospheric nitrogen, thanks to a symbiotic relationship with certain bacteria known as rhizobia found in root nodules of these plants. The ability to form this symbiosis reduces fertilizer costs for farmers and gardeners who grow legumes, and allows legumes to be used in a crop rotation to replenish soil that has been depleted of nitrogen. The nitrogen fixation ability of legumes is enhanced by the availability of calcium in the soil and reduced by the presence of ample nitrogen. Root nodules. via Wikipedia
What puts nitrogen in soil?
Nitrogen fixing bacteria that live in root nodules of members of the legume family of plants. Some Nitrogen is also fixed during lightning strikes.
Which organisms convert nitrogen into a form that is usable by humans?
Bacteria =========================== Specifically a particular type of bacteria that live in nodules on the roots of certain plants (eg the Legume family) called "Nitrogen Fixing Bacteria" . Not other bacteria decompose organic material and release nitrogen back into the atmosphere.
How do plants get nitrogen from the soil?
Nitrogen-fixing bacteria in nodules on plant roots (legume plants; beans, peas, alfalfa) convert nitrogen in the air (ammonia) to nitrites then nitrates which is then absorbed by plants through their roots.
What is the purpose of legume nodules?
They are caused by a symbiotic bacteria which benefits the plant by fixing atmospheric nitrogen (which the plant needs to make proteins).
How do humans get nitrogen we need to make proteins and dna if we can't get it from breathing?
Humans and most other living things are unable to use nitrogen from the atmosphere in their metabolism. The only living things able to use nitrogen from the atmosphere in their metabolism are a small number of species of anaerobic nitrogen fixing bacteria. Several species of nitrogen fixing bacteria are symbiotic with legume plants, the bacteria provide the legume with fixed nitrogen, the legume provides the bacteria isolation from the poisonous oxygen in the air as well as carbohydrates as food. Humans as all other animals, get their fixed nitrogen by eating other animals and/or plants.
How do legumes contribute to the nitrogen cycle?
They absorb nitrogen from the air. Then nitrogen-fixing bacteria convert it to a useable form.
Why cannot green plants absorve gasious nitrogen?
green plants do not have the "power" to break the triple bond of N2 molecule. in better words, they do not have suitable enzymes. on the other hand, some bacteria have, the so colled "nitrogen fixing bacteria", living on legume plant roots.
What kind of plants host bacteria nodules that fix free nitrogen?
Rhizobia bacteria are primarily responsible for pulling nitrogen out of the air and making it available to plants, which then use the nitrogen to create proteins. The legume family (the pea & bean family) of plants are able to form a mutually beneficial relationship with rhizobia bacteria.
